Researchers Want to Know More About Oculopharyngeal Muscular Dystrophy

Oculopharyngeal muscular dystrophy (OPMD) is rare, even among muscular dystrophies, with an incidence of 1 in 100,000 people. It is a late-onset disease, with symptoms typically first appearing after age 50.OPMD gets its cumbersome name from “oculopharyngeal,” meaning that the disease affects the muscles of the upper eyelids and the throat. People with OPMD generally develop droopy eyelids, called ptosis, as well as difficulty swallowing, or dysphagia. They also can experience progressive weakness in the legs.

One in a Million

All the neuromuscular diseases MDA covers are considered rare, meaning they affect fewer than 1 in 20,000 individuals. But within each of those diseases, there are dozens of subtypes defined by the genetic mutations that cause them. Many, if not most, are considered ultra-rare, affecting fewer than 1 in 50,000.

How to Make a Decision About a Clinical Trial

Colleen and Chris Labbadia of Geneva, Fla., became concerned when their son, Brendan, was slow meeting early physical milestones. He was diagnosed with Duchenne muscular dystrophy (DMD) before his second birthday, and when he was 4, they enrolled him in a clinical trial for an experimental drug. "It was the hope for a better future for Brendan," Colleen says.

Expanding Knowledge on GNE Myopathy

Tahseen Mozaffar, MD, is a neurologist and director of the ALS & Neuromuscular Center at the University of California-Irvine. He’s also a leading world expert on GNE myopathy, a form of muscular dystrophy that affects an average of one person per million worldwide.GNE myopathy is caused by mutations in the GNE gene, which is responsible for a step in the production of a sugar called sialic acid. This results in decreased attachment of sialic acid groups to skeletal muscle cells, which is thought to be why the disorder leads to muscle atrophy and weakness.

Express Delivery

Usually, viruses are bad news. But lately, they’re getting good press, thanks to the COVID-19 vaccines created by AstraZeneca, Johnson & Johnson, and Immunity Bio, which use viral vectors to deliver instructions to our cells to fight off the novel coronavirus.Delivering immunity isn’t the only thing viral vectors can do. They also hold great promise in gene-targeted therapies for neuromuscular diseases.

A Little Piece of the Future

Of the 80 patients in the phase 2b international Fulcrum ReDUX4 clinical trial, my mom and I are two. To the trial, we are data — nameless numbers in different age groups from states separated by half the country that met all of the eligibility requirements. To us, we are doing something together to advance science on behalf of everyone living with facioscapulohumeral muscular dystrophy (FSHD).

Support for Your Journey

Why do people contact the MDA Resource Center? There are a lot of reasons, according to Brooke Smith, associate director of the Resource Center.It could be that they or a family member was recently diagnosed with a neuromuscular disease, and they need information about the disease or want to find an MDA Care Center.

Are Vaccines Safe?

Vaccines are big news these days, but what exactly are they?Typically given as a shot, vaccines are an important tool to help prevent people from getting sick with or dying from preventable diseases. Different types of vaccines work in different ways, but they all cause you to develop special cells, or antibodies, that help your body fight a specific disease.

New Research Channels for Myotonia Congenita

Myotonia congenita is an inherited myopathy that prevents affected individuals from relaxing certain muscles after contracting them. The disorder causes muscle stiffness but not atrophy or shrinkage. On the contrary, it often leads to larger, stronger muscles.There are two types of myotonia congenita: Becker disease and Thomsen disease. The Becker type is inherited as an autosomal recessive trait, meaning it is produced when both parents contribute a defective gene. Becker is the more common and more severe form of the disease. It generally shows up between ages 4 and 12, though in rare cases it may occur as late as age 18. Symptoms tend to worsen over time.

The Search for Inclusion-Body Myositis Treatment

Inclusion-body myositis (IBM) is one of the most common disabling inflammatory myopathies in older adults, but its underlying cause is poorly understood.IBM is characterized by progressive muscle weakness and wasting. In patients with the disease, inflammatory cells invade muscle tissue and collect between the muscle fibers. Muscle biopsies of patients diagnosed with IBM reveal multiple “inclusion bodies” containing cellular material of dead tissue.
